Detailed Description

Function Documentation

bool sensor_common_read_reg	(	uint8_t	addr,
		uint8_t *	buf,
		uint8_t	len
	)

Reads a sensor's register over I2C.

Parameters

addr	The address of the register to read
buf	Pointer to buffer to place data
len	Number of bytes to read

Returns

TRUE if the required number of bytes are received

The sensor must be selected before this routine is called.

void sensor_common_set_error_data	(	uint8_t *	buf,
		uint8_t	len
	)

Fill a result buffer with dummy error data.

Parameters

buf	Pointer to the buffer where to write the data
len	Number of bytes to fill

Returns

bitmask of error flags

bool sensor_common_write_reg	(	uint8_t	addr,
		uint8_t *	buf,
		uint8_t	len
	)

Write to a sensor's register over I2C.

Parameters

addr	The address of the register to read
buf	Pointer to buffer containing data to be written
len	Number of bytes to write

Returns

TRUE if successful write

The sensor must be selected before this routine is called.
